Answer:
Small Scale replica of John Hancock tower is approximately 2.33 m.
Step-by-step explanation:
Given:
Height of Willis tower = 1450 ft
Height of John Hancock Center = 1127 ft
Small Scale replica of Willis tower = 3 m
We need to find Small Scale replica of John Hancock tower.
First we will find the per meter scale of Willis tower and then using the same we will use to find the Small Scale replica height of John Hancock tower.
For 3 meter scaling = 1450 ft
So for 1 meter scaling = Number of foots in 1 meter Scaling
By Using Unitary method we get;
Number of foots in 1 meter Scaling =
Now we had 1 meter scaling as 483.333 ft and we need to find meter scaling for 1127.
So again Using Unitary method we get;
Small Scale replica of John Hancock =
Rounding to nearest hundred we get;
Small Scale replica of John Hancock tower is approximately 2.33 m.
The equivalent expression is: 60x - 24 = 12(5x - 2)
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>
60x - 24
We have to find the equivalent expression
The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.
Which is represented as:
a(b + c) = ab + bc
From given expression,
60x - 24
<em><u>Find the greatest common factor of 60 and 24</u></em>
The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24
The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
Then the greatest common factor is 12
Factor out 12 from given expression
Thus equivalent expression is: 60x - 24 = 12(5x - 2)
